Simple terms
Pump pressure switch turns pump on if system pressure goes low enough (35# or 45# depending on pump)
City water inlet has a check valve to prevent pump discharge from leaking out thru connection
Pump has check valve to prevent city water from back-flowing thru pump filling/over flowing fresh water tank
Pump and city water supply same system
Generic RV water System (some minor differences like tank fill, water panel etc) But plumbing Hot/Cold same
